    ”I am so happy!" said Gorilla. "The Great King Ape is coming for dinner!"

    Chimp was happy too, and he jumped up and down.

    "I will cook a great meal for the Great King Ape!" said Gorilla.

    "I will cook too!" said Chimp.

    But Gorilla did not want Chimp t~ cook. He was sloppy. He often made a mess (搞的一团糟). He would ruin (破坏) her great meal. So she asked chimp to buy some drinks.

    When, Chimp came home, he asked, May I cook now?

    "We still need bananas," said Gorilla. "Please pick the best bananas you can find. I want to cook sliced (切片的) bananas for dessert (甜点)."

    Soon Chimp brought back a bag of bananas and put the bag on the kitchen chair. Gorilla walked into the kitchen. She did not see the bag and sat down on the chair. "Oh, no! My bananas! They are ruined!" Gorilla started to cry.

    "Don' t cry, Gorilla," said Chimp. "I have an idea for a nice dessert."

    Chimp took out a big bowl and a spoon (勺子). He peeled (剥皮) some bananas, put them in the big bowl and mashed (捣碎) them with the spoon. Then he put some milk in. At last, Chimp put it into a small bowl.

    Soon the Great King Ape arrived. He ate up all the food. "This is the best meal I have had!" he said.

    Chimp brought out the dessert. The Great King Ape tried it. "Delicious!" he said. "You are both great!"

    "Thank you," said Gorilla. She smiled at Chimp. "Chimp is a wonderful cook," she thought.
